Referring to FIG. 3 shows a view of the wafer container of the first embodiment. The wafer container is a front opening unified pod (FOUP) which includes a container body 10 and a door 20. a plurality of slots 11 is disposed in the inside of the container body 10 to place a plurality of wafers therein, and an opening is located on one of sidewalls of the container body 10 that is provided for loading or exporting or importing of wafer. The doors 20 includes an outer surface 21 and an inner surface 22, in which at least one latch component (not shown) is disposed on the outer surface 21 for opening or closing the front opening unified pod. A recess 24 is disposed on the center portion of the inner surface 22 of the door 20, in which the recess is located between two platforms 25. The wafer restraint used to support the plurality of the wafers within the container body 10 to reduce the size of the wafer container. Furthermore, each wafer restraint module 40 is disposed on the platform adjacent to the edge of recess to restrict the wafer from moving toward the opening of the wafer container, and the number of the wafers is settled down the recess that can be controlled. Furthermore, each two platforms is provided to have a latch component (not shown in Figure) thereon, and a latch opening 23 is formed on the outer surface 21 corresponding to each latch component.

The length of the recess 24 of the inner surface 22 of the door is related to the distance of the slots 11 of the container body 10 and the number of the wafers. For example, the distances between the 12″ or 18″ wafers have been a standard regulation in the industry to obtain the maximum ability of loading and the space is enough to contain the arm to export or import. In general, the number of wafers for the wafer container is 25 pieces. Thus, the length of the recess 24 is constant. However, the width and the depth of the recess 24 of this embodiment can be adjusted. When the width of the door 20 is constant, the depth of the recess 24 can be adjusted to deeper, and the width of recess 24 is also adjusted to wider, so as the whole wafer can place within the recess 24.

Moreover, referring to FIG. 4 and FIG. 5, show the views of the wafer restraint module of the wafer container and fixed on the door. The wafer restraint module 30 is a rectangle bar base portion 31, which includes two longer sides 31L and two shorter sides 31S. One of two loner sides 31L is adjacent the recess 24 to form a plurality of curve portions 32 with a spaced at interval. Each curve portions 32 and the free-ends are constructed to form a semicircle-like protruding portion 32C.

The contacted surface between the guide notch 32G and the wafer can be coated a wear-resisting material, such as PEEK material, to reduce the friction for the wafer. Furthermore, the wafer restraint module 30 can be an integrated structure, and is made of one or two different materials. For example, the base portion 31 and the curve portion 32 are made of one material, and the semicircle protruding portion 32C is made of another material and formed on the curve portion 32. Obviously, the an included angle is located between the base portion 31 with rectangle bar shaped and the curve portion 32, in which the angle is about 10 to 60 degree. The resultant forces is formed toward the central of the wafer when the wafer is restricted by the wafer restraint module (as shown in FIG. 6), and the wafer would not shaken due to the wafer restraint module 30 on two sides of the recess 24 is symmetrical. In addition, the wafer restraint module 30 not only restricts the wafer from moving toward the opening of the wafer container, and the wafer can sink into the recess 24, so that the length of front side and back side can be reduced. As shown in FIG. 4, due to a gap is located between the plurality of semicircle protruding portion 32C on the curve portion 32, thus, the curve portion 32 is elasticity to permit the deformed by crackdown of the wafer.

Furthermore, according to the FIG. 5 and FIG. 6, the base portion 31 includes a plurality of snap holes 33, and a snap pillar 26 is disposed on the inner surface 22 that corresponding to the snap holes 33, thus, the wafer restraint module 30 is firmly on the platforms 25 of the recess 24 of the inner surface 22 of the door 20 by snapping on. For the manufacturing, the wafer restraint module 30 is integrated with the inner surface 22 of door 20 to prevent the slack of the wafer restraint module 30. The integrated structure includes a central hole 34 that corresponding to the recess 24, so that the integrated structure is firmly on the inner surface 22 by snapping on or integrated with the inner surface 22 of the door 20 directly.

Secondly, FIG. 8 shows a view of another wafer container of the second embodiment of this invention. The wafer container is same as the wafer container of the first embodiment, which includes a container body 10 and a door 20. The different between the second embodiment and the first embodiment is that the wafer restraint module 400 is fixed on two sides of the recess 24 of the inner surface 22 of the door 20. As shown in FIG. 9 and FIG. 10, the wafer restraint module 400 on two sides of the recess 24 are formed by a plurality of wafer restraint components 40 with a spaced at interval, and each wafer restraint components aligned the another wafer restraint module 40 on the wafer restraint module 400 that is located on one side of the recess.

Thus, sealing procedure of the door 20 and the container body 10 the bent angle would be changed to make the first contact head 44 that contacted the second contact head 45. Furthermore, the bent portion 42 and the bent arm are made of different two materials, such as plastic with different hardness which can generate the deformation for the curve portion 42 and the bent arm would not deformed easily. The first contact head 44 and the second contact head 45 include a recess respectively, so as the wafer can sink into the recess to avoid the movement of the wafer. Moreover, the plurality of wafer restraint components 40 can form a base portion, in which the base portion is disposed on the inner surface 22 of the door 20 firmly. Certainly, the plurality of wafer restraint components 40 is integrated with the inner surface 22 of the door 29 to reduce the manufacturing cost.

Then, referring to FIG. 11 shows a view of the wafer container of third embodiment of this invention. The apparatus is similar to the wafer container of the second embodiment. The wafer container includes a container body 10 and a door 20. The different is that each wafer container modules 500 is located on two sides of the recess 24 of the inner surface 22 of the door 20 that includes three contact heads, as shown in FIG. 12 and FIG. 13A. The wafer restraint module 50 is located on the two sides of platforms and is arranged by the plurality of wafer restraint components 50. Each wafer restraint components 50 is aligned the wafer restraint component 40 on the wafer restraint module 500 on one side of the recess 24, in which each wafer restraint components 50 include a base portion 51. The one end of the base portion 51 is located on the inner surface 22 of the door 20, and another end is connected to the first bent arm 52, in which the first bent arm includes two free-ends. One of free-ends is located far from the central of the recess 24 that is formed a first contact head 54; another free-end adjacent the central of the recess 24 that contact the second bent arm, and the second bent arm further includes a second contact head 55 and the third contact head 56.

Because the wafer restraint component 50 and the base potion 51 are elastic structure (for example: thermal-elastic plastic structure), includes a bent portion. When the door 20 would be joined with the container body 10, the second bent arm 53 of the wafer restraint component 50 is attached on the surface of the recess 24 in horizontal or suspended on the surface of the recess 24. Thus, the wafer is contacted the first contact head 54 to deform the base portion 51, so as to the included angle of the bent angle would be changed and levered the second contact head 55 and the third contact head 56 to contact the wafer. As showing FIG. 13B, the door 20 is sealed the container body 10, the second bent arm 53 that is far away from the surface of the recess 24 by driven the second contact arm 53. Thus, the restraint body 20 and the wafer contact head 54, the second contact head 55, and the third contact head 56 are contacted the wafer. Obviously, each wafer restraint components 50 include three contact heads for supporting the wafer to restrict the wafer from moving toward the opening of the wafer container. In this embodiment, a pivot 57 is alternatively provided between the two free-ends of the first bent arm 52 and on one side of the inner surface 22 of the door 20, in which the pivot 57 is fixed on the inner surface 22 of door. Thus, when the base portion 51 is deformed or the angle of the curve portion is changed, the first bent arm 52 and second bent arm 53 can be driven so as to the first contact head 54, second contact head 55, and third contact head 56 can attach to the wafer tightly.

According to the abovementioned, each plurality of wafer restraint components 50 can be an elastic integrated structure (for example: thermal-elastic plastic structure). The base portion 51 and the first bent arm 52 or second bent arm 53 also can be made of different materials, or different elastic structure (for example, thermal-elastic structure), such as plastic with different hardness. Thus, bent arm would not be deformed easily due to the deformation of the base portion 51. Alternatively, the first contact head 54, second contact head 55, and third contact head 56 include a recess so as to the wafer is sunk into the recess to restrict the wafer from moving. The plurality of wafer restraint components 50 is formed on the base portion 51, and the base portion is disposed on the inner surface 22 of the door 20.
